Web 2.0
What do you think
Web 2.0 is?
Paradigm shifts
Paradigm shifts
Web 2.0 definition
No definitive definition (still evolving)
Moves the focus to the user of the information, not the creator of the
Information moves “beyond” web sites
Information has properties and these properties
follow each other and find relationships
Information comes to users as they move around
Information is broken up into ‘microcontent’ units that can be distributed
over many domains
Interaction is no longer limited to (X)HTML
Users are able to control how information is categorized and manipulated
User interface becomes a ‘fat’ rather than ‘thin’ client
Requires a new set of tools to remix microcontent in new and useful ways
Another Web 2.0 definition
Web 2.0 is a convergence of individual traits, and social
and technological forces
User-Focused Web = User Satisfaction
Natural result of Web evolution - focus on user
generated content creation and management
Web 2.0 drivers
The “dot-com” collapse forced a web re-examination
Web reached a critical mass
– (Good) information content sources
– Use (and desire for reuse)
– Trust
Web users developed an expectation
of fulfillment
Web 2.0 facilitators
Computing power
 – Still doubling every 18 months (if not less??)
 – PC-based data centers (cloud computing)
 – Low cost, broadband Internet
 – Wireless, broadband access
Web 2.0 facilitators
Device proliferation
 – PDAs, cell phones, etc
Internet standards
 – XML-based integration
User Interfaces
 – many possibilities
Web 2.0 examples
Folksonomy; Internet-based information retrieval methodology consisting
of collaboratively generated, open-ended labels that categorize content such as
Web pages, online photographs, and Web links.
What Web 2.0 is not
Semantic Web (addition of machine-readable
descriptions to content to add meaning
facilitating automated information gathering
and research by computers)
A new collection of technologies
Blogging, wikis (user enabled web editing),
and RSS (Really Simple Syndication) feeds –
these are simple web features
Collective intelligence
Key Element of Web 2.0 –Collective Intelligence
An architecture of participation
Users add value
An evolved Web perspective
User ratings
User tagging

Web 2.0: Rich user experience
Goal of Web 2.0 - A Rich User Experience
Get the user to content they want
Link the user to content they might want
Don’t tell the user how to find content
Let the user decide how to use the content
Do all of the above quickly and efficiently
Web 2.0 Overview
Transition of websites from isolated information silos to sources of
content and functionality, becoming computing platforms serving
web applications to end users
Social phenomenon embracing an approach to generating and
distributing Web content itself
Characterized by open communication, decentralization of authority,
freedom to share and re-use, and "the market as a conversation"
More organized and categorized content, with a far more developed
deep linking web architecture than before
Shift in economic value of the Web, possibly surpassing that of the
dot com boom of the late 1990s
Has lead to a resurgence of excitement around the implications of
innovative web-applications and services
